[Qt]请问 信号的类型为啥不能是std::vector<QString>的？

Question

QObject::connect(pManager, SIGNAL(sglSendAllUseblePortName(std::vector)), this, SLOT(sltGetAllUseblePortName(std::vector)), Qt::QueuedConnection);

Answer 1

connect(pManager, SIGNAL(sglSendAllUseblePortName(std::vector)), this, SLOT(sltGetAllUseblePortName(std::vector)), Qt::QueuedConnection);

改成：

 connect(pManager, SIGNAL(sglSendAllUseblePortName(std::vector<QString> )), this, SLOT(sltGetAllUseblePortName(std::vector<QString> )), Qt::QueuedConnection);
